A list, for your consideration:
26 Garven Dreis
23 Tarn Mison
2 R7
21 Rookie Pilot
4 R2-D2
21 Rookie Pilot
3 R5-P9
---
The concept is simple: fly them in pairs, Garven with the R5 Rookie and Tarn with the R2 Rookie. Garven is the most vulnerable of all the ships, and thus most likely to be focused early - keep him in the rear. This list benefits from a lot of stalling, so don't just joust. If one of your ships is on the verge of death, break off and try to distract your opponent, then come back for a re-attack later.
